W R E N C H A SPECIFICATION forming part of Letters Patent No. 576,454,dated February 2, 1897.

Application filed November 6, 1896. Serial No. 611,256. (No model.)

To all whom, it may cancel-m.

Be it known that I, JOHN H. JENNER, of Leavenworth, in the county ofCrawford and State of Indiana, have invented a new and Improved Wrench,of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved wrench ofthe alligator type, and which is simple and durable in construction andreadily adjustable for engaging and properly gripping pipes, rods, &c.,of diiferent diameters.

The invention consists principally of a re movable jaw and a slidablejaw having its gripping-face at angles to the stock member on which thejaw is fitted to slide.

The invention also consists of certain parts and details andcombinations of the same; as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

pin D, driven transversely in the member A and through an opening in thelug B Now by removing the pin D the jaw B can be swung inward, with theoffset B as the fulcrum, until the lug B is out of engagement with thememberA and then by moving the jaw B transversely the latter can bereadily disengaged from the stock A. Thus whenever the jaw 13 is wornout it can be readily removed and replaced by a new one.

The jaw G is preferably made in. the shape of a casing fitted to slideon the member A and is prevented from dropping off the said member by apin E, attached to the said member and projecting from the sides thereofto engage the sides of the jaw O. Byremoving the pin E the jaw C isslipped off the member A and replaced by a new one whenever necessary.

Now it will be seen that by the arrangement described the movable jaw Ocan be readily slipped or shifted along the member in which similarcharacters of reference indi- A according to the size of the article tobe cate corresponding parts in all the figures. gripped, to make thewrench useful for grip- 2 5 Figure 1 is a side elevation of theimproveping pipes, rods, and the like of different diment.
